The performance 840 is also fitted with a 40-millimetre sound transducer that, with a more focussed bass range, is geared towards the acoustics of modern club music. Both the sophisticated tonal balance and patented S-Logic® Plus technology provide unique reproduction of your favourite music. The decentralised arrangement of the sound transducers creates a spatial sound normally only expected from high-quality speakers. A broad stereo platform with excellent depth graduation allows listeners to completely immerse themselves in the music. This spatial impression is created by the S-Logic® Plus design, which reflects sound more frequently before it reaches the inner ear. This design principle also ensures fatigue-free music enjoyment and protects the hearing. With S-Logic® Plus, compared to conventional headphones, a lower sound pressure level is necessary at the same volume level (3 - 4dB).
